Today I saw a record on the chain about those "coincidental transfers," at first I thought it was another big shot communicating in secret... but after breaking it down, it’s actually pretty simple: A withdraws from CEX and passes through a middleman first, then batches some small accounts to pay startup fees, then moves through the same bridge into L2, finally exchanges into stablecoins in the same batch on the same DEX, with the timing stuck at the same task refresh point. During airdrop season + task platforms, the anti-witchcraft measures make everyone look like they’re clocking in for work, so the paths naturally start to look more and more similar.

Is this money laundering?
Most likely not, just laziness + fear of being flagged, and casually extending the "traces."

Now I mainly look at three things when I see "coincidences": whether the source of funds’ avatar doesn’t look like a hot wallet from an exchange, whether gas/nonce shows signs of batch operations, and whether it overlaps with common routes of certain point-earning tasks. Honestly, a lot of on-chain mysticism ultimately boils down to "convenience"... I do the same—if gas is expensive, I slack off; if gas is cheap, I go on-chain to be a citizen. That’s all for now.
